The SNAP-IDC5G provides four channels of 35-75 VAC/DC digital input. Each channel senses the on/off status for voltages from sources such as proximity switches, push buttons, or auxiliary contacts. The module is ideal for detecting 48 VDC in telecom operations. It has removable top-mounted connectors for easy access to field wiring, as well as channel-specific LEDs for convenient troubleshooting.

SNAP digital input modules are designed to work with SNAP PAC racks and can sense either AC or DC signals. All SNAP digital input modules are compatible with SNAP PAC brains and R-series controllers, including Wired+Wireless models.

Most digital input modules are also compatible with SNAP D-series or legacy M-series and B-series racks and with the brains that mount on them.

Now you can safely and reliably sense and switch industrial-level electrical loads with your Raspberry Pi® and Opto 22 industrially hardened digital I/O.

This Selection Guide describes compatible I/O racks and modules, power supplies, and accessories that work with the Raspberry Pi and the Digital I/O Carrier Board for the Pi (OPTO-P1-40P). Specifications, dimensional drawings, and wiring diagrams for racks and I/O modules are included.
